Hello,

I am trying to add three y-Axis to a chart Model. But if I display the chart at least two axis are overlapping depending on the axis.Position.

Is there any possibility to relocate an axis?

Best regards

Benjamin

hi Benjamin, see the "AxesDemo" in the WPF solution. I will add the demo to the ExampleLibrary shortly, then you can also see it in the Silverlight and Windows Forms project.

The "Position" property of the axes sets the position of the axis to left, right, top or bottom of the plot area.

The axes also have "StartPosition" and "EndPosition" properties - these fractions define where the axis starts and ends in the left/right/top/bottom axis areas.

Dear Objo, 

please see the example of the link below. I am looking for a possibility to display axis like this. At the bottom of the chart there are two axis below each other. If I render the same chart in OxyPlot, then the two axis are overlapping.

Thanks for the link. I think it is a good idea! (but I am not sure if designers like this kind of look...)

I suggest a 'PositionOffset' property to be added to the Axis class - this will move the position of the axis vertically for a horizontal axis and v.v. It would also be great to have auto positioning of the axis - but this will require more passes in the measure/arrange algorithm.

I add the suggestion to the issue tracker. Also, feel free to create a patch on this feature!

Currently the MouseDown event includes the HitTestResult element, but the MouseUp (or MouseMove) don't seem to have it. I can also not find in the source if I am mistaken. 

Would it be possible to include the HitTestResult element in the MouseUp event, or is there an easy way of calculating the closest element myself?

objo wrote at 2012-05-11 00:16:

You are right, currently the hit testing is only performed on the mouse down event. Similar code can be added to the mouse up event, will consider adding it later. See the source code for the mouse down event how you can find the closest element, it should be possible to copy/paste the code.

Hi

I have a plot with 10 points and need to retrieve the data for the intermediate points from code much like the tracker does when clicking the plot series.

As an example...

I have 10 points making up the data points on a smoothed line series plot.

I need to be able to retrieve the data value for a point at an arbitrary point along the X-Axis (eg X=3.2) that falls on the smoothed plot.

I have looked through the code and cannot find a function that can retrieve this information easily without the user clicking the plot series.

Thanks in advance..

BTW: great plotting package, love it.

objo wrote at 2012-11-07 16:19:

The tracker only finds the nearest point, it does not interpolate. I don't think there is any interpolation functions implemented in the library yet.

But we need to add this for http://oxyplot.codeplex.com/workitem/10017.

JasonWeise wrote at 2012-11-07 19:20:

Hi 

Thanks for the reply.

How can this be the case when, if you click on the smoothed plot curve the tracker gives you an X,Y value that is not in the original data set (ie it is smooth interpolated between the points) 

For example if I have 5 data points in the plot within a smoothed line series and I click anywhere on the series "between" the points I get a value at that point I clicked displayed by the tracker. I want to be able to get that calculated value from the series in code without the user clicking the line series.

If I want the value of the plot 1/6 of the way between the points (2.5,24) and (3.4,35) I need to be able to get this info from the plot without the user having to click 1/6 of the way between the points.

objo wrote at 2012-11-07 19:36:

It finds the *nearest* point, not necessary the point at the x-value of your mouse cursor.

You find the code in OxyPlot\Series\XYAxisSeries.cs method GetNearestInterpolatedPointInternal

Is it possible to exchange the behavior of the left and right mouse buttons? So that the left mouse button can be used for panning and zooming. If yes, how can this be done?

Thanks

Hi,

I think I've stumbled upon a memory leak when dynamically generating plots. Imagine something like this:

<ItemsControl ItemsSource="{Binding}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Vertical" />
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <oxy:Plot Model="{Binding}" Height="300"/>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

Even though the context changes, "old" plots remain hooked and, after profiling, I'm pretty sure the CompositionTarget.Rendering event is the culprit.

I eagerly await your comments on this.

Thank you

objo wrote at 2012-04-19 21:29:

thanks for the notice, I have planned to do some memory profiling, will try to get it done soon.

I have implemented a weak event manager for the rendering event in the helix toolkit, this should be possible to use.

anomistu wrote at 2012-04-20 14:14:

I saw that you've had a similar problem on the helix project, however the weak event manager you've used over there is not available in SL.

Another problem is that in SL the CompositionTarget class is static, not abstract, as in WPF, so it can't be used as an argument to most weak event listeners available out there that use generics when subscribing.

I am trying to get it to work but I don't succeed:

I want to display outside temperatures for a complete year with 1 hour interval values. (so I have 8760 value pairs).

for the horizontal axis I use a DateTime axis. But I have trouble setting the right settings for the horizontal axis.

I've set the MajorStep to 0.125 to display the majorgridlines each 3rd hour.

But I don't get the Minor gridlines to display. (settting MinorStep to 0.04166666666)

I checked in a little change that let you set the MinorStep on the DateTimeAxis.
